How to do UNION in an XML output

How to do union in an XML output
I have a requirement that I need to combine the results of 2 queries and get the final XML output. Typically this sound very easy and can b
be done with a simple UNION operator. But my query is a hierarchical query with CURSOR at the column level
For example
SELECT
EMPNOm
CURSOR(
          SELECT
                    DEPTNO
                    FROM
                    DEPT
                    WHERE
                    EMPNO = :EMP_NO) AS DEPT
FROM
EMP
In oracle 9i UNION is not allowed in nested queries. One workaround is to populate the data from query one in a temp table and then from query 2 finally fetch the data from this temp table.
Can this requirement be fulfilled in any easirer way using SQLX or something else. Please suggest me .
Thank You

I'm afraid I have no idea what you are trying to achieve with Query you have posted. Can ypu provide some idea of what you would want the output of the query to look like given the data in the EMP and DEPT tables and a given value of EMPNP...
